+1) Sell any products or be used as a statement of endorsement in promotional material of unrelated products.
+2) Be used in a way that could tarnish the image of the project (e.g. breaking our code of conduct).

+
+Created by ZILtoid1991.
+
+### Things that are not recognized as branding materials:
+
+* Icons and other graphical assets made specifically for the engine and its tools. They're under the same Boost License as the engine, and can be used in other projects.
+* Other assets used in testing of the engine. See their own license and/or creators on information about use of theirs.
+* Any non-officially recognized mascots.
+
+## Examples of things that are allowed
+
+* Using any of the branding materials or their variants in splash screens in games (or any other software) that are made with the engine and does not negatively reflect on the project as a whole.
+* Using the logo in tutorials covering the engine (books, videos, etc.).
+* Using the logo in advertisements of games (or any other software) that are made with the engine and does not negatively reflect on the project as a whole.
+
+## Examples of things that are not allowed
+
+* Using it on your application that is entirely unrelated to and/or does not make use of the engine.
+* Using it for promotional material for a game written with an other engine.
+* Making a fork of the project, calling it "PixelPerfectEngine" and using the same resources.
+* Using it in a game featuring elements that could negatively reflect on the project itself.
+* Selling PixelPerfectEngine branding assets as NFTs or selling unofficial merchandise with our branding resources on them.
+
+## Stance on Erotic Games
+
+While the PixelPerfectEngine project in itself has nothing against games of this nature, we do reserve the right to not provide support to developers of games which we either find to be in bad taste, and/or are illegal in certain countries.
+
+## Stance on Cryptocurrencies and NFTs
+
+You are not under any circumstance allowed to use PixelPerfectEngine's branding assets to promote anything to do with blockchain, cryptocurrency or NFTs.
+We will not accept any donations in the form of cryptocurrency either.
